BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an improved emulsion polymerization process utilizing ethylenically unsaturated amine salts of sulfonic, phosphoric and carboxylic acids. More specifically, the invention relates to emulsion polymerization processes which utilize ethylenically unsaturated amine salts of alkylbenzene sulfonic acids, alkyl olefin sulfonic acids, alkyl alcohol sulfuric acid esters, or alkoxylated alkyl alcohol sulfuric acid esters, fatty acids, and fatty phosphate acid esters, or mixtures thereof, to form polymers, discrete solid polymeric particles and latexes. Additionally, the present invention relates to the use of the salts to impart improved adhesion, hydrophobicity, resistance to film yellowing, scrubability, anti-blooming, hydrolytic stability and shear stability characteristics to polymer emulsions and latex formulations.

[0003] 2. Description of the Related Art

[0004] The emulsion polymerization of ethylenically unsaturated monomers to form discrete solid polymeric particles for use in coating, sealant, adhesive and/or elastomer (CASE) applications is well known to the art. Conventional emulsion polymerization of ethylenically unsaturated monomers employs one or more water soluble surfactants to emulsify the monomers and the resulting polymer products, i.e., latexes. The monomers used in emulsion polymerization reactions are generally water-insoluble, but in some cases may be water-soluble. During a typical emulsion polymerization, a surfactant is used to suspend small portions of monomer in a continuous or semi-continuous aqueous phase. Typically, the monomer molecules are suspended as small spheres in the aqueous phase, wherein the polymerization takes place within the small spheres. The water soluble surface active agents, i.e., surfactants, typically utilized in emulsion polymerization reactions are anionic, nonionic, and cationic surfactants or a mixture thereof.

[0005] The polymeric particles formed by the emulsion polymerization process are typically utilized in coating, sealant, adhesive and/or elastomer (CASE) applications. In a traditional emulsion polymerization reaction, the surfactant does not become chemically bonded to the polymeric particles by carbon-carbon bond formation but rather remains in the polymeric particle product solution after the emulsion polymerization reaction is complete, i.e., all of the monomer(s) is reacted. The unreacted surfactant can have a detrimental effect on the polymer product solution, as it can interfere with the performance of such polymerization products in CASE applications; the suspension of polymeric particles may become destabilized over time and undergo unwanted coagulation. The unreacted surfactant may cause unwanted pealing of a latex paint coating on a substrate, and decreased moisture and scrubability resistance in other various CASE applications. Additionally, residual surfactant can cause an undesirable “blooming” that leads to surface irregularities in a resulting CASE material that is applied to a substrate.

[0006] Several proposals have been made in the prior art to employ a polymerizable surfactant as the surface active agent during an emulsion polymerization reaction. U.S. Pat. No. 5,478,883 (incorporated herein by reference in its entirety) describes the use of ethylenically unsaturated polymerizable water-soluble nonionic surfactants formed by the reaction of a diallylamine compound with ethylene oxide, propylene oxide or butylene oxide, in emulsion polymerization reactions. Similarly, U.S. Pat. No. 5,162,475 (incorporated herein by reference) provides alpha-beta ethylenically unsaturated poly(alkylenoxy) polymerizable surface active compounds for use in emulsion polymerization. For additional examples of polymerizable surfactants for use in emulsion polymerization processes, see U.S. Pat. Nos. 4,377,185 and 4,049,608.

[0007] Non-polymerizable surfactant solutions to the traditional problems encountered in performing an emulsion polymerization process are numerous. U.S. Pat. No. 3,941,857 describes the use of epoxy resins which react with the residual anionic, cationic or nonionic surfactant. Polymerizable compounds such as allyl alcohol (and esters thereof) have been found to be ineffective due to the formation of undesirable high levels of coagulum in the final emulsion polymerization product. Additionally, see U.S. Pat. No. 4,224,455.

[0008] Thus, there is a need for an emulsion polymerization process for forming polymers and discrete polymeric particles that are well suited for use in coatings (e.g., latex paints, electro-deposition, container, paper and paperboard, can coatings, industrial coatings, automotive coatings, textile coatings), adhesive (e.g., water- and non-water borne adhesives, pressure sensitive adhesives, binders), sealant (e.g. floor finishes, films, binders, non-woven binding materials such as carpet backing, glass fibers) and elastomer (CASE) applications.

SUMMARY OF THE INVENTION

[0009] The present invention utilizes a novel group of compounds in the form of ethylenically unsaturated amine salts of sulfonic, phosphoric and carboxylic acids, which display surface activity, i.e. they are surfactants. It has been discovered that these compounds function as reactive surfactants, i.e. surface active agents in polymerization processes, particularly emulsion polymerization processes. The surface active agents of the present invention are capable of polymerizing with themselves (to form homopolymeric surface active agents) and/or are capable of co-polymerizing with other ethylenically unsaturated monomers of the type which are commonly employed in polymerization processes. The polymerizable surface active agents utilized in the present invention are prepared from readily available, economical raw materials, and generally, their preparation does not require any special handling or equipment.

Somewhat preferably, the nitrogen atom is linked covalently, directly or indirectly, to the ethylenically unsaturated moiety of the nitrogenous base.

[0019] The polymers prepared utilizing the polymerizable surface active agents of the present invention may be used as the primary resin component or a minor resin component of a resin mixture which is used to prepare latexes, coatings, adhesives, sealants, elastomers, binders, inks, floor finishes and the like.

[0034] These and other objects and advantages, as well as the scope, nature, and utilization of the claimed invention will become apparent to those skilled in the art from the following detailed description and claims.

BRIEF DESCRIPTION OF THE DRAWINGS formulation prepared according to Example #1. DETAILED DESCRIPTION OF THE INVENTION

[0035] A method is provided for forming polymers utilizing polymerizable surface active agents, wherein the method comprises: (1) preparing a mixture comprising at least one ethylenically unsaturated monomer and at least one polymerizable surface active agent; and (2) polymerizing the mixture. Generally, any ethylenically unsaturated monomer that is capable of undergoing polymerization may be utilized in the present invention. The method of the present invention is particularly well suited to emulsion polymerization but may also be conducted as a solution polymerization, suspension polymerization, micro emulsion polymerization or inverse emulsion polymerization. The polymerization may be conducted in any manner known to the art, including but not limited to, free-radical initiated polymerization, thermal initiated polymerization and redox initiated polymerization using, for example, batch, continuous, or controlled monomer feed processes, known conditions of stirring time and temperature, and known kinds of additives such as initiators, surfactants, electrolytes, pH adjusting agents, buffering agents, protective colloids and the like. In general, the polymerization process of the present invention will be carried out from about 20° C. to about 120° C. (e.g., between about 50° C. and about 110° C.). These polymerization temperatures will vary with respect to the reactivity and concentration of the polymerization initiator being used. Batch polymerization times may vary depending on the method of polymerization and the monomers being polymerized. Such times may vary from about 2 to about 10 hours. In general, the mixture may be a solution, emulsion, suspension or dispersion of the ethylenically unsaturated monomer and the polymerizable surface active agent. Further, the polymerizable surface active agent may be provided to the mixture as an aqueous solution.

[0036] In accordance with the present invention, polymerization may occur simultaneously as the mixture is being formed (i.e. as the monomer and the polymerizable surface active agent come in contact, a self-initiating polymerization occurs). Accordingly, the present invention also encompasses a method for continuous polymerization, utilizing at least one ethylenically unsaturated monomer and at least one polymerizable surface active agent.

[0037] The polymerizable, surface active agents utilized in the present invention are salts or quaternary nitrogen compounds comprising:

[0038] a) at least one acid, wherein the acid is a sulfonic acid, a carboxylic acid, or a phosphoric acid, or a mixture thereof; and

[0039] b) at least one nitrogenous base, wherein the nitrogenous base contains at least one nitrogen atom and at least one ethylenically unsaturated moiety.

[0040] The polymerizable surface active agents are generally capable of polymerization with themselves, co-polymerization with the ethylenically unsaturated monomer or co-polymerization with a partially polymerized polymer particle. In a somewhat preferred embodiment, the polymerizable surface active agent is partially (i.e. 150 percent by weight of the polymerizable surface active agent) consumed by polymerization with itself, co-polymerization with the monomer and/or co-polymerization with a partially polymerized polymer particle. In a more preferred embodiment, the polymerizable, surface active agent is substantially (i.e. 50-90 percent by weight of the polymerizable surface active agent) consumed by polymerization with itself, co-polymerization with the monomer and/or co-polymerization with a partially polymerized polymer particle. In a most preferred embodiment, the polymerizable, surface active agent is substantially completely (i.e. greater than 90 percent by weight of the polymerizable surface active agent) consumed by polymerization with itself, co-polymerization with the monomer and/or co-polymerization with a partially polymerized polymer particle.

[0041] The polymerizable surface active agent and the monomer are generally combined in a ratio of about 0.01:1 to about 3:1 on a weight basis. In a preferred embodiment, the polymerizable surface active agent is present in the mixture in a concentration of about 1-100 weight percent, based on the total weight of the ethylenically unsaturated monomer present in the mixture. In a more preferred embodiment, the polymerizable surface active agent is present in the mixture in a concentration of about 1-20 weight percent, based on the total weight of the ethylenically unsaturated monomer present in the mixture.

[0042] In general, the method of preparing polymers in accordance with the present invention does not require the use of a non-polymerizable surfactant, i.e. the mixture is substantially free of non-polymerizable, surface active agents. However, in a somewhat less preferred embodiment, the mixture further comprises a supplemental, non-polymerizable surfactant (iii); wherein the supplemental surfactant is a sodium, potassium, calcium, magnesium, or ammonium salt of a substantially saturated anionic surfactant, or a nonionic, cationic, or amphoteric surfactant, or a mixture thereof; and wherein the supplemental surfactant is provided in a concentration of about 0.01 to about 20.0 percent by weight, based on the total weight of polymerizable surface active agent and supplemental surfactant provided in the reaction zone.

[0043] The present invention provides pre-polymerization mixtures comprising (1) at least one ethylenically unsaturated monomer; and (2) at least one polymerizable surface active agent; wherein the ethylenically unsaturated monomer and the polymerizable surface active agent are defined as above or below. This pre-polymerization mixture may be polymerized by a variety of initiation methods known to the art.

[0044] The present invention provides polymers comprising: (1) at least one monomer unit; and (2) at least one surface active agent unit; wherein the monomer unit is derived from an ethylenically unsaturated monomer; wherein the surface active agent is derived from a polymerizable surface active agent; and wherein the ethylenically unsaturated monomer and the polymerizable surface active agent have co-polymerized to form the polymer.

[0045] In another embodiment, the present invention provides a method for forming polymers, wherein the method comprises (1) preparing a mixture comprising at least one ethylenically unsaturated monomer, at least one acid, wherein the acid is a sulfonic acid, a carboxylic acid, or a phosphoric acid, or a mixture thereof, and at least one nitrogenous base, wherein the nitrogenous base contains at least one nitrogen atom and at least one ethylenically unsaturated moiety; and (2) polymerizing the mixture. In accordance with this embodiment, the acid and the nitrogenous base may form a polymerizable, surface active agent in situ; wherein the polymerizable, surface active agent is a salt or quaternary nitrogen compound; wherein the polymerizable surface active agent is capable of polymerization with itself, co-polymerization with the ethylenically unsaturated monomer and/or co-polymerizing with a partially polymerized polymer particle; and wherein the polymerizable, surface active agent is substantially completely consumed by polymerization with itself, co-polymerization with the monomer and/or co-polymerization with a partially polymerized polymer particle. In one alternative, the nitrogenous base may partially or completely co-polymerize with the ethylenically unsaturated monomer, followed by formation of a surface active agent (i.e. complexation/salt formation with the acid). Without being bound by any particular theory, it is believed that the nitrogenous base is incorporated into the polymer back-bone and the acid forms an ion pair, i.e. a salt, with the nitrogen atom of the nitrogenous base, thereby adhering to the polymer and forming a positively charged nitrogen atom. In another alternative within the purview of this embodiment, a portion of the nitrogenous base may polymerize with itself, co-polymerizes with the ethylenically unsaturated monomer or co-polymerize with a partially polymerized polymer, followed by complexation/salt formation with the acid. In another alternative, the nitrogenous base may partially or completely co-polymerize with a homopolymeric surfactant, followed by complexation/salt formation with the acid.

[0048] The present invention provides homopolymeric surface active agents. These homopolymeric surface active agents are formed by polymerizing at least one polymerizable, surface active agent, wherein the polymerizable, surface active agent is a salt or quaternary nitrogen compound comprising at least one acid, wherein the acid is a sulfonic acid, a carboxylic acid, or a phosphoric acid, or a mixture thereof; and at least one nitrogenous base, wherein the nitrogenous base contains at least one nitrogen atom and at least one ethylenically unsaturated moiety.

[0049] The homopolymeric surface active agents of the invention are generally capable of polymerization with themselves, co-polymerization with the monomer or co-polymerization with a partially polymerized polymer.

[0050] In another embodiment, the present invention provides a method for forming polymers, wherein the method comprises: (1) partially polymerizing at least one ethylenically unsaturated monomer to form a partially polymerized polymer/monomer mixture; (2) adding to the partially polymerized polymer/monomer mixture at least one polymerizable surface active agent and/or at least one homopolymeric surface active agent, to form a partially polymerized polymer/monomer/surface active agent mixture; and (3) polymerizing the partially polymerized polymer/monomer/surface active agent mixture; wherein the homopolymeric surface active agent being a polymer formed by polymerizing at least one polymerizable, surface active agent; wherein the polymerizable, surface active agent is a salt or quaternary nitrogen compound comprising at least one acid, wherein the acid is a sulfonic acid, a carboxylic acid, or a phosphoric acid, or a mixture thereof, and at least one nitrogenous base, wherein the nitrogenous base contains at least one nitrogen atom and at least one ethylenically unsaturated moiety.

Polymerizable Surface Active Agents

[0064] The polymerizable surface active agents utilized in the present invention are salts or quaternary nitrogen compounds comprising at least one acid, wherein the acid is a sulfonic acid, a carboxylic acid, or a phosphoric acid, or a mixture thereof, and at least one nitrogenous base, wherein the nitrogenous base contains at least one nitrogen atom and at least on ethylenically unsaturated moiety. The polymerizable surface active agents is usually present in the mixture in a concentration from about 0.01-100.0 percent by weight based on the total weight of the ethylenically unsaturated monomer. In general, although not required, the polymerizable surface active agents have a homophilic/lipophilic balance (HLB) of less than about 45. In a somewhat more preferred embodiment, the polymerizable surface active agents have an HLB of about 5-40. The polymerizable surface active agents are generally capable of polymerization with themselves, co-polymerization with the ethylenically unsaturated monomer, or co-polymerization with a partially polymerized polymer.

[0065] More specifically, while the nitrogenous base may be capable of some degree of surface activity, in the present invention it is the acid portion of the polymerizable surfactant that is responsible for the surfactant character and the HLB of the compound. In preferred embodiments, the nitrogenous base contributes little or no surfactant character to these materials. In other words, the acids are generally capable of acting as surfactants when they are present as anions of the acid and the associated counterion is any positively charged species. The most common positively charged species are sodium, potassium, ammonium, calcium and magnesium ions. In fact, the acid portion of the polymerizable surfactant may be supplied as a sodium, potassium, or other salt of the carboxylic, phosphoric or sulfonic acid and then combined with the nitrogenous base to form the inventive surfactant.

[0066] The polymerizable surface active agents of the present invention are prepared from readily available, economical raw materials, and generally, their preparation does not require any special handling or equipment. The polymerizable surface active agents may be prepared in a batch mode or a continuous mode; they may be prepared by contacting nitrogenous base with the acid or contacting the acid with the nitrogenous base. By contacting it is meant that the acid(s) is added to the nitrogenous base and the components are mixed, or the ethylenically unsaturated amine(s) is added to the acid(s) and the components are mixed. The acid may be present as an anion and the base may be present as a cation (i.e. a quaternary nitrogen) in the mixture. The acid and nitrogenous base are in the form of salts or quaternary nitrogen compounds. As known by one skilled in the art, upon mixing the acid and nitrogenous base together, the nitrogenous base becomes a conjugate acid and the acid becomes a conjugate base.

[0067] The surface active agents and blends of surface active agents may be prepared in a variety of forms such as, for example, liquids, solutions, solids, powders, flakes, semi-solids, gels, “ringing” gels, G-phase liquids, hexagonal phase solids, or thick pastes. The surface active agents may be spray dried, flaked, extruded, and the like. Although not critical to the present invention, the polymerizable surface active agents may be prepared “neat” or in a conventional solvent such as water, low molecular weight alcohol or hydrocarbon, or a mixture thereof, to produce a solution of the polymerizable surface active agent. The present invention encompasses polymerizable surface active agents as salts in dry form and as aqueous solutions.

Additionally, isethionic acid ethylenically unsaturated amine salts may be prepared by esterifying a fatty acid, a fatty acid alkyl ester or a fatty acid chloride with the sodium salt of isethionic acid, followed by ion exchange with the ethylenically unsaturated nitrogenous base, such as allyl amine. Optionally, isethionic acid, or its sodium salt, may be combined with the ethylenically unsaturated nitrogenous base, such as allyl amine, to produce the isethionic acid allyl amine salt, which may then be esterified with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

[0146] Generally, it is advantageous to not use conventional, non-polymerizable surface active agents in the present invention. However, if so desired, the polymerizable surface active agents of the present invention may be used in the polymerization in combination with minor amounts of a conventional polymerization surfactants, i.e. supplemental surface active agents, that are not polymerizable. Without being bound by any particular theory, these supplemental surface active agents may allow for the varying of particle size of the resulting discrete, solid, polymeric particles. The supplemental surface active agents are generally anionic, nonionic, cationic or amphoteric surfactants or mixtures thereof, and are typically used as in a concentration of about 0.01 to about 20.0 percent by weight, based on the total weight of surface active agents (i.e. both polymerizable and non-polymerizable). Somewhat more preferably, the supplemental surface active agents are used in a concentration of about 0.01 to about 5.0 percent by weight, based on the total weight of supplemental surface active agents (i.e. both polymerizable and non-polymerizable).

[0147] Suitable supplemental nonionic surface active agents are generally disclosed in U.S. Pat. No. 3,929,678, Laughlin et al., issued Dec. 30, 1975, at column, 13 line 14 through column 16, line 6, incorporated herein by reference. Generally, the supplemental nonionic surface active agent is selected from the group comprising polyoxyethylenated alkylphenols, polyoxyethyleneated straight chain alcohols, polyoxyethyleneated branched chain alcohols, polyoxyethyleneated polyoxypropylene glycols, polyoxyethyleneated mercaptans, fatty acid esters, glyceryl fatty acid esters, polyglyceryl fatty acid esters, propylene glycol esters, sorbitol esters, polyoxyethyleneated sorbitol esters, polyoxyethylene glycol esters, polyoxyethyleneated fatty acid esters, primary alkanolamides, ethoxylated primary alkanolamides, secondary alkanolamides, ethoxylated secondary alkanolamides, tertiary acetylenic glycols, polyoxyethyleneated silicones, N-alkylpyrrolidones, alkylpolyglycosides, alkylpolylsaccharides, EO-PO block polymers, polyhydroxy fatty acid amides, amine oxides and mixtures thereof.

These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to 12 carbon atoms in either a straight or branched chain configuration with the alkylene oxide. In a preferred embodiment, the ethylene oxide is present in an amount equal to from about 1 to about 25 moles of ethylene oxide per mole of alkyl phenol.

The hydrophobic portion of these compounds preferably has a molecular weight of from about 1500 to about 1880 and exhibits water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially available Pluronic® surfactants, marketed by BASF.

(Optionally, the hydrophobic group is attached at the 2-, 3-, 4-, etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside.) The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6-positions on the preceding saccharide units.

The glycosyl is preferably derived from glucose. To prepare these compounds, the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1-position). The additional glucosyl units can then be attached between their 1-position and the preceding glycosyl units 2-, 3-, 4-, and/or 6-position, preferably predominately the 2-position.

Examples of suitable chain transfer agents include bromoform, carbon tetrachloride, carbontetrabromide, bromoethane, C1-C₁₂ alkyl mercaptans, e.g., dodecylmercaptan, thiophenol, and hydroxyalkyl mercaptans, e.g., mercaptoethanol.

[0178] The amount of agglomerated polymers, or “coagulum”, in the resulting lattices at the conclusion of the polymerization is determined by collecting the agglomerated polymers using a 20 mesh screen that has openings sufficiently large enough to allow the discrete un-agglomerated polymers to pass, rinsing the collected agglomerated polymers with water, and weighting the remaining agglomerated polymers trapped on the screen. The percent coagulum is calculated by dividing the weight of the coagulum by the theoretical weight of the entire latex based upon the weights of the ingredients used for the polymerization reaction.

[0179] The viscosity of the resulting lattices following polymerization is determined by using a RV Brookfield synchro-lechtric viscometer equipped with a No. 3 spindle. During such determinations 950 ml of each latex is placed in a 1000 ml beaker and the viscometer operated at 25° C. and 60 rpm.

[0180] The mechanical stability of the lattices following exposure to mechanical stress is evaluated to determine the extent to which there is a change in the viscosity and/or the visual presence of coagulum. More specifically, two cups of each latex are placed in a five-cup stainless steel Hamilton Beach blender, and the blender operated at medium speed until the latex coagulates. Failure of the latex is the point at which coagulum separation can be visually observed; a longer time of blending at medium speed without coagulum separation, i.e. a longer time before failure, is a highly desirable characteristic of a latex.

[0181] Solids of lattices were determined by concentrating the latex at 120° C. in an oven to remove all volitiles, and subsequently weighing the residue. The pH of each solution was measured using an Orion 210 pH meter. Particle size was measured using a Nicomp 370, [submicron analyzer, (up to 2 microns)].

[0182] The particle size of the resulting lattices is determined with a NICOMP 370C Auto-dilution particle size analyzer using standard methods and procedures for operation of such equipment and such data recorded for 50% volume in units of nano-meters.

[0183] The water sensitivity, e.g. hydrophobicity, of the resulting lattices was determined by ASTM D724-45.

[0184] All ¹H NMR spectra were recorded using a 270 MHz Joel Delta NMR Fourier Transform Spectrometer. Chemical shifts (δ) are reported in parts per million (ppm) down field from tetramethylsilane (TMS) using internal TMS or residual non-deuterated solvent as a reference. NMR data for all samples was acquired by dissolving the solid sample in CD₃OD.

[0185] The allylamine and propyl amine may be obtained from Aldrich Chemical Company (USA).

[0186] In the following examples, all amounts are stated in percent by weight of active material unless indicated otherwise. One skilled in the art will recognize that modifications may be made in the present invention without deviating from the spirit or scope of the invention. The invention is illustrated further by the following examples which are not to be construed as limiting the invention or scope of the specific procedures or compositions described herein.

EXAMPLE 1

[0187] A methylmethacrylate/butylacrylate/methacrylic acid (MMA/BA/MMA) co-polymer (in a weight ratio of about 48:49:3), in combination with the allylamine salt of dodecylbenzenesulfonic acid (ADDBS), is prepared as follows. About 254 g of deionized water and about 10.6 g of ADDBS (as a 22% active aqueous solution), are placed in a reactor suitable for emulsion polymerization, equipped with agitation means, heating means and cooling means. With agitation, the reactor is purged with nitrogen (99% pure), and heated to about 80-82° C. The temperature of the reactor contents is adjusted to about 77-79° C., and about 75 g of the monomer mixture (20% of a total of 374 g of the MMA/BA/MMA monomer mixture in the ratio above) is added to the reactor. After 10 minutes, 16.9 g of a solution of ammonium persulfate (20% of the total solution of 1.9 g of ammonium persulfate dissolved in 82.5 g of water) is added to the reactor over a period of about 7 minutes with continued agitation, during which time there is an exotherm of about 7-10° C. After the exotherm is complete, about 299 g of the monomer mixture (the remaining 80% MMA/BA/MMA monomer mixture), 64.5 g of the ammonium persulfate solution (the remaining 80%), and 15.55 g of ADDBS (as the 22% active aqueous solution) are simultaneously charged to the reactor over a period of 2 hours with continued agitation, while keeping the reactor contents at a temperature of about 78-81° C. The reactor temperature is then elevated to about 82-84° C. with continued agitation, for about 15 minutes. After this 15 minute period, the reactor is cooled to about 30° C. The resulting latex product is completely removed from the reactor and gravity filtered using a first 20 mesh screen and then a second 250 mesh screen. The total latex coagulum (i.e. solids) from both mesh screens is collected, combined and weighed. Various physiochemical properties of the latex are reported in Table II.

[0188] FIG. I depicts the partial ¹H NMR spectrum, showing the region of δ5.0-8.0, of the allylamine salt of dodecylbenzenesulfonic acid (ADDBS). The peaks centered around 7.4 ppm are signals corresponding to the aromatic protons of the benzene ring. The signals at about 5.9 ppm and 5.3 ppm correspond to the protons of the double bond in the allyl amine portion of the compound.

[0189] FIG. II depicts the partial ¹H NMR spectrum, showing the region of δ5.0-8.0, of a latex formulation prepared according to Example # 1 above. As can be seen in FIG. II, the double bond signals from he allyl amine portion of the compound, at 5.9 ppm and 5.3 ppm, are absent from the spectrum. Without being bound by any particular theory, the double bond has been substantially completely consumed during the polymerization reaction.

[0199] The hydrophobicity of a latex prepared using a typical non-polymerizable surfactant was compared to that of a latex prepared using a representative polymerizable surfactant of the present invention. It has been discovered that the latex prepared in Example 1 (using ADDBS) possess remarkable hydrophobicity, as compared to the latex prepared according to Example 1 (using the ammonium salt of dodecylbenzene sulfonic acid, AmDDBS). [Need to insert ASTM method and description here.] The change in contact angle as a function of time for a water droplet at each of the latex film surfaces was measured; the results are shown below.

[0200] Without being bound by any particular theory, a rapidly increasing contact angle as observed from a latex film indicates that the water droplet is penetrating the film due to surfactant related imperfections of the film. A constant water droplet contact angle, as in the case of the ADDBS derived latex, indicates the desirable result whereby water is unable to penetrate the hydrophobic film.

[0201] In a test similar to the contact angle measurements, the hydrophobicity of a latex prepared using a typical non-polymerizable surfactant was compared to that of a latex prepared using a representative polymerizable surfactant of the present invention, whereby the different latex films were coated and heat cured onto porous filter paper and treated with water. As observed in the results shown below, water undesirably, readily penetrated through the film and absorbed into the paper in a few seconds for the latex derived from the AmDDBS surfactant. However, the latex film derived from the ADDBS surfactant, did not allow the water to penetrate or absorb; the water droplet maintained its original shape on the latex film, prior to being influenced by evaporation effects (at least thirty minutes).

[0202] The adhesion properties of a latex prepared using a typical non-polymerizable surfactant were compared to that of a latex prepared using a representative polymerizable surfactant of the present invention. It has been discovered that the latex prepared in Example 1 (using ADDBS) possess a vastly superior adhesion profile, as compared to the latex prepared according to Example I (using the ammonium salt of dodecylbenzene sulfonic acid, AmDDBS). Adhesion data were collect for each latex acrylic lattice using ASTM method D897. This test method is a standard test for adhesion called “block pull”; results from the test are indicated in pounds per square inch (p.s.i.), wherein the higher the p.s.i. obtained, the better the adhesion properties of the latex. Adhesive failure is defined as the point at which the latex, upon application of a pulling force, no longer adheres to the surface of the substrate. Cohesive failure is defined as the point at which the latex itself fails, i.e. where the latex splits into two or more portions, but remains bound to the substrate. The adhesion tests were conducted using an Instron Model 1123, with a 5000 pound load cell, a sample size of 0.5 g of latex, a surface area of 4 in², whereby the treated sample blocks were allowed to dry at room temperature (i.e. 25° C.) for three days under 0.25 p.s.i. external pressure. Aluminum and steel blocks were prepared by sanding with extra fine 220 grit paper until smooth to the touch. A weighed amount of each latex (0.5 g) was placed on one surface of one block and another block place on top for three days. Failure was determined by visual inspection, with the results indicated below. Latex Surfactant Adhesive Failure (p.s.i.) AmDDBS (non-polymerizable)  65 ADDBS (polymerizable) 170

[0203] The latex film yellowing properties of a latex prepared using a typical non-polymerizable surfactant were compared to that of a latex prepared using a representative polymerizable surfactant of the present invention. It has been discovered that the latex prepared in Example 1 (using ADDBS) possess a greatly improved film yellowing profile, as compared to the latex prepared according to Example 1 (using the ammonium salt of dodecylbenzene sulfonic acid, AmDDBS). Latex film yellowing was compared after aging the films six months at room temperature, at approximately standard atmospheric conditions. It is highly desirable, as known by one skilled in the art, to produce a latex film which does not yellow upon application to a surface, with the passage of time. After a period of 6 months, the ADDBS-derived latex was plainly observed to be significantly lighter color than the AmDDBS-derived latex. Absorbence measurements were taken for each latex at 350 nm and 420 nm; the lower the absorbance at a given wave length, the lighter the latex (i.e. the less yellow the latex). Results of the measurements for the two latexes are shown below. Latex Absorbance Latex Surfactant 350 nm 420 nm AmDDBS (non-polymerizable) 16.9 5.3 ADDBS (polymerizable) 10.0 2.5

[0204] The scrubability properties of a latex prepared using a typical non-polymerizable surfactant were compared to that of a latex prepared using a representative polymerizable surfactant of the present invention. It has been discovered that the latex prepared in Example 1 (using ADDBS) possess improved scrubability characteristics, as compared to the latex prepared according to Example 1 (using the ammonium salt of dodecylbenzene sulfonic acid, AmDDBS). Scrubability of the latexes was evaluated using ASTM scrub test D2486. Seven Star Acrylic Flat House Paint, 103A100 White, from Ace Hardware was utilized in the testing. The ADBBS- and AmDDBS-derived latexes were individually added to the paint in a ratio of 2:1 (latex:paint).

[0205] FTIR comparisons were conducting by casting latex films on glass, derived from both ADDBS and AmiDDBS. The films were dried at room temperature for several days, removed from the glass and aged at room temperature, at approximately standard atmospheric conditions, for six months. The films were individually placed on a ZnSe plates and the FTIR spectra recorded. Peak heights were measured on the absorbance peak located at 1035 cm⁻¹ (i.e. the S═O stretch peak) for each film. It has been discovered that the latex prepared in Example 1 (using ADDBS) possess a much lower peak height absorbance in the FTIR spectrum, as compared to the latex prepared according to Example 1 (using the ammonium salt of dodecylbenzene sulfonic acid, AmDDBS). Without being bound by any particular theory, a lower the peak height absorbance indicates a desirable characteristic of the latex, whereby the individual surfactant molecules are not present at the surface of the latex film, i.e. they have not migrated to the surface of the film.
